I have no idea what you've done, and why your board isn't working as shipped. *You* need to do some troubleshooting, figure out what the problem is. Then fix it. Think of this as a good learning experience.
If the board is booting, and you have a serial debug cable already, then you do not exactly *need* a sdcard. However, like the serial debug cable. Having an sdcard around, can be very handy. How would you propose to fix the eMMC file system if you ever put it in a non bootable state ? Anyway, I would probably start with *ifconfig* on both sides of the connection. To see why a connection is not happening. Passed that, *route -n*, and *lsmod* may come in handy too.
